Are there a lot of suppliers of Physical Web beacons?

There are and the list is always growing. Google maintains a list of those who are certified by them for various different types of protocols and we choose to focus on utilizing the Eddystone-URL frame because we can do all of the security that Eddystone-EID provides within our BKON firmware and we think the overwhelming majority of push messages from iBeacons and possibly UID are just bad for users.

All of the Eddystone-URL beacons listed on Google's site are compatible with BKON Platform as long as they are configured to broadcast Eddystone-URL protocol. Our BKON beacons are configured for Eddystone-URL by default so there is no need for a configuration app. We do, however, have a configuration app if you decide you want to change the default hardware configuration, though. For info on our configuration app called BKON Configuration, check out our tutorials and app docs.
